Can you take Advil (ibuprofen) with methotrexate?
For many people, taking Advil (ibuprofen) with methotrexate can raise methotrexate levels and increase the risk of side effects, especially if you take higher-dose methotrexate, have kidney problems, are dehydrated, or also take other interacting medicines. [1][2]
Methotrexate is cleared by the kidneys, and nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can affect that clearance. That’s why clinicians often advise caution (or avoidance) with NSAIDs during methotrexate therapy. [1]
When is the risk higher?
The interaction risk is more likely when any of these apply:
- Methotrexate dose is higher (for example, used in cancer regimens, or higher RA dosing in some cases). [1]
- Kidney function is reduced (chronic kidney disease) or you’re dehydrated (vomiting, diarrhea, poor fluid intake). [1][2]
- You take other drugs that also raise methotrexate exposure (for example, some antibiotics such as trimethoprim-sulfamethoxazole, or other NSAIDs). [1][2]
If you fall into one of these groups, you should contact your prescriber or pharmacist before using ibuprofen.
What symptoms would suggest methotrexate toxicity?
Seek medical advice promptly if you develop signs that could reflect methotrexate side effects, such as:
- Mouth sores or unusual mouth pain
- Unexpected bruising or bleeding
- Severe sore throat or infections
- Unexplained fever
- Severe nausea, vomiting, or diarrhea
- Shortness of breath or persistent cough [1][2]
What can you take for pain or fever instead?
Because ibuprofen is an NSAID, many patients are advised to use an alternative first, most commonly acetaminophen (paracetamol), assuming you have no liver disease and you stay within the recommended daily dose. Confirm with your pharmacist because the “best” option depends on your methotrexate dose and other medications. [1][2]
What should you do right now?
If you already took Advil once, don’t panic, but you should:
- Check with your pharmacist or methotrexate prescriber about whether it’s safe for your specific regimen.
- Avoid additional NSAIDs until you get guidance.
- Be extra careful to stay hydrated and monitor for side effects. [1][2]
